WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 232,573, datedSeptember 21, 1880.

Application filed July 2-1, 1880. (No model.)

To all whom it may concern:

Be it known that I, B. N. TORREY, acitizen of the United States,resident at Oreston, in the county of Union and State of Iowa, haveinvented certain new and useful Improvements in WVindow-Screens 5 and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

This invention has relation to windowscreens; and it'consists in thefeatures of c0nstruction and combination hereinafter fully described,and particularly pointed out in the claims.

Figure 1 is a front elevation of a window having niyimprovedwindow-screen frame applied. Fig. 2 is a horizontal sectional view online a a, Fig. 1; and Fig. 3 is a similar view on line b 1), showing thescreen-frame bowed inward in position to be inserted in place in thewindow-frame.

Referring by letter to the. drawings, A dessignates the window-frame inwhich the screenframe is to be used to exclude insects and (usingsufficiently heavy material) burglars, and at the same time admit freshair to the apartment in which it is employed.

The screen-frame is constructed in two parts, B and O, rabbeted on theirinner edges, as at D, to form a joint when the parts are united.

The bar E of the part B is provided with a projecting arm, F, and thestile G and bar H of the part C are recessed at I to receive theprojecting arm F. The arm F and the recess 1 are upon the inner side ofthe screen-frame. The bar H of the part 0 is also provided with ametallic slide, J, which slides over the projecting arm F after thelatter has been fitted enter the spaces between the strips N of thewindow-frame, and be then pushed outward until the two parts are in thesame vertical plane in the window-frame and locked by pushing the slideover the arm F.' The pins K also en gage with the wood-work adjacent tothem and assist in retaining the screen-frame in place.

The locking mechanism being on the inside, the screen-frame cannot beopened from the outside of the window, and is therefore a protectionagainst burglars as well as insect-s.

This screen-frame is cheap, durable, and efficient, and its constructionand operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawings.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-- Awindow-screen constructed in two parts, B and O, rabbeted on their innervertical edges, connected by an arm, F, projecting from one part andfitting a recess, I, in the other, and locked by a metallic slide, J,when uni-ted substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

BARTLETT NORTON TORREY.
